I agree. Its not even 1 grade math how its possible to make such a mistake and make me rethink ten times to add up to those .10

Even through this has no impact for solution, but man this math is bad.
On description we have sum: 1041(that's ok), 1083.86 (but real sum is 1083,681) and 1128.30 (with real sum: 1128.111921). This is really confused me

Your solution is just buggy. It does not handle trailing whitespace correctly. It is not a kata issue.

You're likely looking for the OrderBy method instead.

If you Google "linq order enumerable" you'll find this kind of information easily :)

C# experts is it that normal i have this message with System.Linq, System.Collections and System.Collections.Generic directives included in my solution ?
error CS1061: 'IEnumerable' does not contain a definition for 'Order' and no accessible extension method 'Order' accepting a first argument of type 'IEnumerable' could be found (are you missing a using dire

I have a feeling, that this should be 6 kue.

Maybe add tag "combinatorics"?

That was easier than I thought

Oh hell no, this kata really gave some time to think about how to optimize lists and tasks

Even though I didn't solve this kata at moment when I saw your comment, but now - yes. I was really amazed by how many ways you could solve this kata

Could you give some hint for thinking about that?

In sample test at 'add_cash' ans is 'Jeff has 118', but in really 'Jeff has 88' *In python

Я пытаюсь оптимизировать как могу код, но он просто не хочет работать настолько быстро настолько нужно. Может есть у кого-нибудь подсказки? На питоне не очень много места для моневров, а какого-то невероятного математического решения я не смог найти
